安徽枞阳地区出土先秦青铜器的初步科学分析

On the Scientific Analysis about the Bronze Objects of the Pre-Qin Period Unearthed from Zongyang Area Anhui Province

为了揭示枞阳地区出土铜器所蕴涵的科学信息,本文对枞阳文物管理所藏的部分先秦青铜器进行了初步检测分析。结果表明,22件样品中有11件锡青铜、7件铅锡青铜、4件铅青铜,所有检测的青铜器均为铸造而成,部分铜器有铸后受热迹象;青铜剑的制作工艺较为复杂,部分铜剑使用了错金、镶嵌及复合剑的制作工艺。尽管此次分析的样品数量有限,尚不足以全面揭示枞阳地区出土先秦青铜器的材质和制作工艺特征,但为继续研究该地区青铜技术、区域青铜文化特征以及探讨该地区与其他地区青铜文化的关系提供了科学依据。

This paper presents the results of a preliminary examination of 20 bronzes unearthed from the Zongyang County which is the important area for culture communication between the north and the south in An- hui Province. 22 samples obtained from the 20 Western Zhou Dynasty and Eastern Zhou Dynasty bronzes in- cluding ritual vessels and weapons have been examined by using optical microscope and SEM-EDS. The ex- amination results show that the samples include Cu-Sn alloys, Cu-Sn-Pb alloys and Cu-Pb alloys, which all manufactured by casting. Tin content of bronze swords is higher, and some bronze swords use inlaying gold and bimetallic sword manufacturing techniques. The high content of alloying elements and close connection between composition and usability of different objects imply a quite sophisticated skill of metalworking.
